Interface SerializerTrace

All Known Implementing Classes:
TransformerImpl

public interface SerializerTrace

This interface defines a set of integer constants that identify trace event types.

Usage:
**For internal use only**

Field Summary
static int EVENTTYPE_CDATA
          Event type generated after CDATA is generated.
static int EVENTTYPE_CHARACTERS
          Event type generated for character data (CDATA and Ignorable Whitespace have their own events).
static int EVENTTYPE_COMMENT
          Event type generated after a comment has been added.
static int EVENTTYPE_ENDDOCUMENT
          Event type generated when a document ends.
static int EVENTTYPE_ENDELEMENT
          Event type generated when an element ends, after it's children have been added.
static int EVENTTYPE_ENTITYREF
          Event type generate after an entity ref is created.
static int EVENTTYPE_IGNORABLEWHITESPACE
          Event type generated for ignorable whitespace (I'm not sure how much this is actually called.
static int EVENTTYPE_OUTPUT_CHARACTERS
          Event type generated when characters are written to an output stream.
static int EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS
          Event type generated when characters might be written to an output stream, but these characters never are.
static int EVENTTYPE_PI
          Event type generated for processing instructions.
static int EVENTTYPE_STARTDOCUMENT
          Event type generated when a document begins.
static int EVENTTYPE_STARTELEMENT
          Event type generated when an element begins (after the attributes have been processed but before the children have been added).

Field Detail

EVENTTYPE_STARTDOCUMENT

public static final int EVENTTYPE_STARTDOCUMENT
Event type generated when a document begins.

EVENTTYPE_ENDDOCUMENT

public static final int EVENTTYPE_ENDDOCUMENT
Event type generated when a document ends.

EVENTTYPE_STARTELEMENT

public static final int EVENTTYPE_STARTELEMENT
Event type generated when an element begins (after the attributes have been processed but before the children have been added).

EVENTTYPE_ENDELEMENT

public static final int EVENTTYPE_ENDELEMENT
Event type generated when an element ends, after it's children have been added.

EVENTTYPE_CHARACTERS

public static final int EVENTTYPE_CHARACTERS
Event type generated for character data (CDATA and Ignorable Whitespace have their own events).

EVENTTYPE_IGNORABLEWHITESPACE

public static final int EVENTTYPE_IGNORABLEWHITESPACE
Event type generated for ignorable whitespace (I'm not sure how much this is actually called.

EVENTTYPE_PI

public static final int EVENTTYPE_PI
Event type generated for processing instructions.

EVENTTYPE_COMMENT

public static final int EVENTTYPE_COMMENT
Event type generated after a comment has been added.

EVENTTYPE_ENTITYREF

public static final int EVENTTYPE_ENTITYREF
Event type generate after an entity ref is created.

EVENTTYPE_CDATA

public static final int EVENTTYPE_CDATA
Event type generated after CDATA is generated.

EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS

public static final int EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS
Event type generated when characters might be written to an output stream, but these characters never are. They will ultimately be written out via EVENTTYPE_OUTPUT_CHARACTERS. This type is used as attributes are collected. Whenever the attributes change this event type is fired. At the very end however, when the attributes do not change anymore and are going to be ouput to the document the real characters will be written out using the EVENTTYPE_OUTPUT_CHARACTERS.

EVENTTYPE_OUTPUT_CHARACTERS

public static final int EVENTTYPE_OUTPUT_CHARACTERS
Event type generated when characters are written to an output stream.
